Specification 242,901 is referred to. The discs are spring-pressed against the ring 2, which, in the form shown in Fig. 2, is formed externally as a pulley engaged by a belt 5. The rings 2 of two such single units may be connected by a belt or by a rigid intermediate friction ring. In a form shown in Figs. 12 and 13, the ring 2 engages two pairs of friction cones 3, 3<1>, encircling both. Multiple parallel arrangements similar to both Fig. 2 and Fig. 12 are described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form in which the ring member is hollow, the cones or bevel discs being spring-pressed apart within it.
